/* ** ** Swift/XRT hardness ratio for QSO B1727+502. ** Hardness ratio for this file has been calculated by splitting the data at 2.0 keV. ** ** Data taken from the automatic processing at http://www.swift.psu.edu/monitoring/ ** ** When using these data and results in publications, please reference M.C. Stroh & A.D. Falcone 2013, ApJS, 207, 28; arXiv: 1305.4949. ** ** Key: ** ** BinCenter - Center of time bin (MJD). ** BinHW - One-half of the full time bin size (days). ** FracExp - Conversion factor between bin size and observing time. ** Ratio - Source hardness ratio (2.0 - 10.0 keV)/(0.3 - 2.0 keV). ** This is also Rate2/Rate1 from the following columns. ** RatioError - 1 sigma error in the hardness ratio. ** Mode - 0 if in Windowed Timing (WT). ** 1 if in Photon Counting (PC). ** Rate1 - The background subtracted, PSF corrected and pile-up corrected source count rate (cts/s) in the 0.3 - 2.0 keV band. ** RateError1 - 1 sigma error in source count rate (cts/s) in the 0.3 - 2.0 keV band. ** NetRate1 - Background subtracted count rate (cts/s) in the 0.3 - 2.0 keV band. ** NetError1 - Error in the background subtracted count rate (cts/s) in the 0.3 - 2.0 keV band. ** Rate2 - The background subtracted, PSF corrected and pile-up corrected source count rate (cts/s) in the 2.0 - 10.0 keV band. ** RateError2 - 1 sigma error in source count rate (cts/s) in the 2.0 - 10.0 keV band. ** NetRate2 - Background subtracted count rate (cts/s) in the 2.0 - 10.0 keV band. ** NetError2 - Error in the background subtracted count rate (cts/s) in the 2.0 - 10.0 keV band. ** ** ** Upper limits have an error listed as -1.00000. ** */ BinCenter BinHW Ratio RatioError FracExp Mode Rate1 RateError1 NetRate1 NetError1 Rate1 RateError2 NetRate2 NetError2 57881.984341 0.001409 0.22900 0.05691 1.00000 1 0.44150 0.04785 0.36042 0.03906 0.10110 0.02261 0.08248 0.01844 57881.987347 0.001598 0.20122 0.04947 1.00000 1 0.44322 0.04529 0.36189 0.03698 0.08919 0.01994 0.07273 0.01626 57881.990557 0.001612 0.17907 0.04358 0.98198 1 0.50347 0.04832 0.41057 0.03940 0.09016 0.02016 0.07340 0.01641 57881.993433 0.001235 0.21846 0.05398 0.98824 1 0.53730 0.05646 0.43759 0.04598 0.11738 0.02625 0.09524 0.02130 57881.995656 0.000988 0.31361 0.08023 0.97059 1 0.47741 0.05932 0.38746 0.04814 0.14972 0.03348 0.12121 0.02710 57881.998314 0.001670 0.27154 0.05922 0.96636 1 0.43804 0.04430 0.35600 0.03600 0.11895 0.02298 0.09682 0.01871
